PURPOSE

The RSA5D-..T series controllers (hereinafter “Device”) are used to control the output of three-

phase fans by step changing of the supplied voltage.

The controller has ve speed settings which correspond to ve xed positions of the rotating knob

on the front panel.

TECHNICAL SPECIFICATIONS

Supply Voltage: 400 V/50 Hz

Fan Motor Nominal Voltage: 400 V/50 Hz

Lead-In: screw terminal block 0.5 ... 4.0 mm2

Operating Ambient Temperature: +5°C..+40 °C

Protection Class: IP44

DESIGN AND OPERATING PRINCIPLE

The device is a three-phase transformer enclosed in an ABS plastic casing. The device front panel

(see Fig. 1) features speed selector 1, signal lamp 2 which indicates normal operation of the control-

ler, and signal lamp 3 which corresponds to controller operation in the emergency mode.

The controller has ve speeds selectable by means of rotating knob 1 to one of the ve xed

positions or “O” (O). The controller is equipped with TK terminals (see Fig. 4) for connection of the

thermal contact built into the fan motor. When actuated the thermal contact cuts voltage supply to

the fan motor and switches on signal lamp 3 which indicates controller operation in the emergency

mode. The controller also has terminals L1,N (230VAC/Max. 2A) for connection of external equipment

(e.g. air damper actuators). Setting the controller knob to “О” cuts the voltage supply to the fan mo-

tor.

Fuse 6 (see Fig. З) prevents the device and the connected fan from excessive current consump-

tion.

The controller application range is limited by the fan electric motor characteristics. The fan elec-

tric motor must be designed for voltage regulation by means of a transformer.

The speed controller and its connected equipment may present an electric shock hazard. There-

fore, the device shall be connected and operated only by adequately qualied sta familiar with

this manual. The speed controller belongs to electrical machinery with voltages up to 1,000 V.

The device must be disconnected from the power mains for any and all operations with the de-

vice internals.

The speed controller shall only be used with single-phase motors. The total current consumption

of the electrical appliances connected to the device shall not exceed the limit value (see Techni-

cal specications). The speed controller must be properly earthed.

Use the device with due caution. Do not subject it to shocks and overloads or expose it to liquids

and dirt. Should any foreign objects penetrate onto the controller circuit board, disconnect the

unit from the mains and remove them.

Do not apply overvoltage to any of the speed controllers parts while testing the device (e.g.

with a megohmmeter etc.). Disconnect the cable from the speed controller prior to any measure-

ments on the cable or motor!

DO NOT:

Operate the device in the presence of smoke or smell commonly associated with burning insula-

tion, elevated noise or vibration, in case of structural integrity loss or formation of cracks in the

casing or with broken connectors;

Cover the device with any materials, mount any gauges and objects on top, block the vents or

ll them with any foreign objects; do not use the device in areas with an explosive or chemically

aggressive environment detrimental to metals and insulation or under the inuence of droplets

or spray; do not use outdoors;

Connect any electric motors (individual or part of any equipment) with the phase current con-

sumption (usually stated on the nameplate) in excess of the limit phase load current for the de-

vice;

Connect the device output terminals to the power mains.

INSTALLATION AND SETUP

Check the device visually for any damage to the casing;

Remove the front panel by unscrewing self-tapping screws 7 (see Fig. 2);

Fasten the controller to the mounting surface using mounting holes 8 (see Fig. 2) in the rear wall

of the unit;

Complete the electrical connections according to the wiring diagram (see Fig. 4). The external

wires are connected to the device by means of bolt-and-nut terminals 5 (see Fig 3). The cables are

routed into the unit through sealed lead-ins 4 (see Fig.3). The external lead-in (220V/50Hz) must

be equipped with an automatic switch built into the stationary wiring. Supply the power voltage

and start the device.

ATTENTION! Following the device transportation or storage under temperatures below

zero let the unit warm up in the specified operating conditions for at least 4 hours.

TECHNICAL MAINTENANCE

Periodically clean dust, bres and other contamination from the ventilation holes.

Make sure the external wires are tightly connected to the screw terminals of the devi

TRANSPORTATION

The device shall be carried in the manufacturer’s packing without limitation to the means of trans-

port, distance or speed. Once received by the user the devices shall be stored in the original packing

at temperatures ranging from -40 to +35 °C and relative humidity up to 80%. The storage premises

shall be free from dust and corrosive acid or alkaline vapours.

WARRANTY

The manufacturer warrants trouble-free operation of the speed controller over the period of 12

months from the sale date within the warranty storage period. The warranty storage period is 24

months from the manufacturing date. If the sale date and vendor’s stamp are missing, the warranty

period shall be calculated from the manufacturing date. The customer shall be entitled to free repair

of the device in case of any malfunction of the controller occurring through the manufacturer’s fault

within the warranty period.

ATTENTION! The manufacturer shall not be liable for any injuries or damage caused by

non-compliance with the installation and operation regulations set forth herein.

ATTENTION! Check the controller certicate of sale and acceptance for completeness (the

required information includes the manufacturing and sale dates, manufacturer’s and ven-

dor’s stamps).
